<h3>Subdivision of Hillsides</h3> <p>Lands having slopes of 10% or greater shall use the following procedure to calculate the maximum density allowable.</p> <ul> <li>Prepare a contour map at a vertical interval of not more than 5 feet, or not more than 10 feet where the natural slope exceeds 15%. The map shall be certified as complying with the following standard of the United States National Map Accuracy standard, revised June 17, 1947, by the registered land surveyor or registered engineer presenting or preparing the map.</li> <li>From the contour map, prepare a slope map using the following slope classifications:</li> <li>Slope Range 0% - 10%, Land Use Classification RA-3</li> <li>Slope Range 10% - 15%, Land Use Classification RA-5 and RA 7.5</li> <li>Slope Range 15% - 30%, Land Use Classification RA-10</li> <li>Slope Range 30% and greater, Land Use Classification RA-20</li> <li>From the slope map, measure the acreage in each slope range and divide by the minimum lot size of the corresponding land use classification (RA-3, RA-5, RA-7.5, RA-10, RA-20) to establish the density allowed for each slope range. The base density allowed for a lot of record shall be the sum of the number of dwelling units allowed for the slope ranges.</li> <li>The total number of proposed lots shall not exceed the base density allowable based on the slope map information.</li> <li>A lot in a proposed subdivision shall contain at least 0.8 of a dwelling unit according to the slope analysis; the overall number of subdivision lots, however, shall not exceed the total number of dwelling units for the entire lot of record upon which the subdivision is proposed.</li> </ul>
This section provides the procedure for calculating the maximum density allowable for lands with slopes of 10% or greater.
